citizen of the, Republic of Germany, residing at Zeesen- Koennge-i V'usterhnusennear -Ber-,

lin, Germany, have invented'certain new and useful Improvements-im'Devioes for Inserting Rivets (forv'vhich I' have. filed applied: tions in Germany March, 28,1917, January 21.1918, MarchQO, 1918, April 17, 1918,-a-nd April 24, 1918); and I do hereby declere'the to lowing to be efull, elm, and exeetdescription of the invention, such as will are able others skilled in the art to which it" rtains to make and use the sa'me, this app ice;- tion, being a division from apphcation for a. patent on improvements-1n p1pe"oi nts filed April 25th,--1919, bearing Serial ber 292,767;

My invention relates to iinprovements in devices for inserting'or placing rivets 111 e pipeor hollow girder insuohpos'ition as to e'rmit the outer end pf the"ins'erted rivet to c upset or riveted a'geinst the-materiel be ing joined or riveted, andmore particularly to :1, tool adapted-for use in placing rivets in previously-formedholesin pi es or-girdere for formin jointsibetween t em; such asthe joining o the tubular ties or girde'rs' In joining two or more p1pes,:or MIN 8tin'g the-braces to the it is very tedious an iflicult to. rivets in the'respective holes when. he :pipes are of small diameter and-the rivets cannot be introduced directly by hand.

The object of my invention is to provide a tool adapted to receive and hold a. rivet, and, when inserted or introduced into a ipe, to place the rivet into previously onned registering holes in the pipes to be joined.

These objects are attained by the apperatus shown in the accompanying drawings, in which Fig. 1 is a side view, a'rtly in sec tion, of the tool as it eppears w enepplymg 1 nrivet through ahole in a pi e. 2 is a horizontal sectional view t en just above the leaf spring 14 in Fig. 1. 3 is a to plan view of the front end of t e tool, on Fig. 4 is a front view of the tool and pipe; similar reference characters denoting simi lar parts throughout the several views.

ties on the inside, I

seetheears orpoints, 5 and 6, with a substantially V-sheped tapering opening 7 between them, whlch tztpers rearwardly to the point 8, where 1t 13 of the same size as the rivet hole, and 1s for the purpose ofreceiving the shank of the-rivet,

A slide 8 is provided, which is reciprocata ble vertically in the outer end of the head 2, its motion being;- constrained by guides 10 in the head and verticnl'slots 12 in the slide, and is provided with. a semiseircu-la-r depres sion' 1.3 in which the head of the rivet is mounted or seated. At 14 is a. leaf spring, secured to the interior surface of theupper wall? of the head 2 by means of rivet 15, or other suitable means, the Bifurcated outer end of this leaf spring 14 embracing the shank of the rivet and holding it in place- The slide 9 iso ereted and slid vertically by means of o, b l crank lever 16-, pivoted on it pin '17, this pin 17-extendin transversely-on the head 2. The forwei leg or member 18 of the bell-crank lever is inserted in a slot 19, in the-slide 9, while the other leg or member 20 of the bell-crank lever is givotslly connected to a pivoted hand-lever 1, pivoted upon the reerwardly extending tubular portion 3. At 22 is a. stationary handle, also-mounted'onthe tubular extension 3. i

In order to retein the slide 9 in its normal position at the lower end of the slots 12, when not bei held up by the lever 16, a leaf spring 23 18 secured to the upper rtion of the inside wall of the head 2, on its free end bears on top of the slide 9.

At 24 is e ipe or tubular girder within which the too is shown as having just inserted n rivet.

In the operation of the apparatus a rivet is placed on the slide 9 with its head in the depression therein, the rivet being held with its shank in a vertical position by means of the leaf sprin 14, the shank of the rivet passing thro h the bifurcated outer end of the head 2. he bell-crank lever 16 is then operated and. the' -lesg1 18 moves spire-rd, and

in turn moves the ide 9, and thus causes the rivet to be inserted in'the rivet hole provided in the pipe. After the operation of inserting the rivet effected, the slide 9 and other parts are perinitted to assumetheir original position by the action of the spring 23.

I claim: i 1. In a portable tool for inserting rivets,
